The invention relatesto co1npresses;fand has for one of its obects to so construct a compress that it may be alternatively used for compressing material to standard or high density. Another object is to construct the compress with an intermediate invertible platen, which maybe secured to either of the relatively movable platens ofthe com-' press to cooperate with one in compressing, the material to 'standard density-and to corf operate with the other to compress the material to high density. A further object is to so construct the compress that the intermediate platen may be readily inverted.

such as cotton, to standard density differs from a compress for compressing material, such as cotton, to high density, where both have the same relative movement of platens by having each of its relatively movable platens ofgreater width and consequently greater area than the platen of the high density compress opposite the high density attachment, The compress for compressing material, such as cotton, to standard density'has .2 the same parts as the compress for compressing cotton to high density.

As shown, the compress has the upper and lower relatively movable platens 1 and 2,

respectively, the upper platen being stationary andthe lower platen being reciprocable toward and away from theupper platen and having a fixed stroke limit. The lower platen has a width and consequently an'area less than that of the upper platen so that this lower platen may be reciprocated between the sideplatens 3 of thehigh density attachment when the compres'sis a high density compress. 1 isan intermediate platen havmg a face 5 of substantially the same width and i area as the lower face 6 of the. upper platen 1 and opposed face 7 of substantially the same width and area as the upper face 8 of the lower platen. Thisintermediate platen is invertible and may be fixedly secured alternatively to the upper and lower platens by suitable means such as the bolts 9. As

shown in Figure 1, theintermediate platen 7 is fixedly secured to the, lower platen to present its face 5, opposed to the lower face 6 of the upper platen. ,As shown in Figure l'tl'n-i invertible platen is fixedly'secured to j the upper platen to present its face 5 opposed to the upper face 8 of'the lower platen. In

A the former instance the compress is a standard'density compress, while in the latterin stancethe compress is -a high density compress, the side platens 3 ofthe high density attachment clearing the face 5 of the inter:

mediate platen when these side platensare in operative position. i i

' To facilitate converting'the compress from a standard density to a-high density compress orvice versa, the intermediate platen 4 is provided'at its opposite ends 'withthe aligned holes 10, in which may be engaged the pins 11.- Flexible members, such as the chains 12, aresecured' at their upper ends to the opposite ends of the upper platen 1 and at their lowerends'to the pins 11, the lengths of-these flexible members being such that when the pins 11 are connectedto the intermediate platen the flexible members will suspend the intermediate platen from the ,upper platen at a height such that the intermediate platen maybe swung about the pins,

the lower platen at this timebeing sufficiently below the" intermediate platen toprovide' the necessary clearance. As shown in Figures 1 and 2,.the lower platen 2 carryingv the in-' ciently toprovide .for inserting, the. pin 11 into the holesilO inthe intermediate platen. The bolts Q'having been removed, the lower platen is then lowered a sufficient distance to permit swingingfof the intermedi ate platen about thepins 1 1 and inverting this interme-- diate platen, Figure'3 showing the parts 'during this inverting operation. A suitable blocking means 13is' then 'placed'upon the termediatev platen has been raised sufli alternately attaching 5 in place, the compress now being ready upon removal of the blocking means to operate as a high density compress. I

With this construction, 1t will be seen that the compress may be used either for compresshigh density. It will also be seen that the compress in either case has the same parts, which, however, are differently combined or arranged. It will be further seen that we have provided a simple methodfor converting the compress.

What we claim as our inventionis:

1. A compress having relatively movable platens with opposed faces of different areas, and an intermediate invertibleplaten forming a permanent part of the assembly and having faces corresponding in areas to the areas of the faces of said relatively movable platens.

2. A compress having relatively movable upper and lower platens with lower and upper work faces respectively, said upper face having a greater area than said lower face, and an intermediate invertible platen with opposite faces corresponding in areas to the areas of said lower and upper faces and means for alternately securing said intermediate platen to said relatively movable platens.

3. A compress having relatively movable 5-,platens with opposed faces of different widths and an intermediate invertible platen forming a permanent part of the assembly and having faces correspondingin widths to the widths of the faces of said relatively mov- 40. able platens.

4;. A compress. having relatively movable upper and lower platens with opposed faces of different widths, an intermediate invertible platen with faces corresponding in widths to the widths of the faces of said upper and lower platens, and means for temporarily suspending said intermediate laten from said upper platen, including a exible member for connecting said intermediate platen to said upper platen.

5. A compress having relatively movable platens with opposed faces ofdifferent areas, an intermediate platen having a face corre- 55 sponding in area to one of the faces aforesaid and means for alternately attaching Qaplatens with opposed faces, one of said faces having a width substantially greater than the width of the otherface, and an intermediate platen havinga face corresponding in width to the first-mentioned face and means for said ing material, such as cotton, to standard or intermediate,

platen to the relatively movable platens aforesaid.

7. A compress having relatively movable platens with opposed faces of different widths and an intermediate platen having faces corresponding in width to the faces of said relatively movable platens and means for alternately attaching said intermediate platen to the latter platen.

8. A compress having relatively movable upperand lower platens with opposed faces of different widths, an intermediate invertible platen. with faces corresponding in widths to the widths of the faces of said upper and lower platens, and means for temporarily supporting said intermediate platen fro-m one of the aforesaid platens to, permit inverting said intermediate platen.

9. A compress having relatively movable platens with opposed faces of different areas, an intermediate invertible platen having a face substantially corresponding in area to one of the faces aforesaid, and means for alternately securing the opposite face of said intermediate platen in engagement with the J opposed faces aforesaid of the relatively movable platens.
